Hydroxypivaldehyde is the organic compound with the formula HOCH2(CH3)2CCHO. A colorless liquid, it is produced by condensation of formaldehyde and isobutyraldehyde:
- CH2O + (CH3)2CHCHO → HOCH2(CH3)2CCHO
The compound is a rare example of a distillable aldol (3-hydroxyaldehyde). Upon standing, it dimerizes reversibly to the dioxane derivative.
Applications
Hydroxypivaldehyde is a precursor to vitamin B5 as is practiced commercially.
Hydroxypivaldehyde is also a precursor to neopentyl glycol by hydrogenation:
- HOCH2(CH3)2CCHO + H2 → (CH3)2C(CH2OH)2
